1 Claim.

The present invention relates to a suspension mounting particularly adapted for mounting in suspension an electrical unit-in axial alignment with the mounting and in a predetermined longitudinal position as shown in my copending application.

More specifically my suspension mounting is particularly adapted for mounting a condenser or the like in the chassis of the usual radio set.

In such structures it isimportant that the condenser not only be maintained in proper vertical alignment but in a predetermined position against longitudinal movement'and against accidental displacement by unintentional abnormal 1 strains, such as grasping the condenser and lifting upwardly on the set or pushing downwardly on it as frequently happens in use, or other strains and stresses set up in handling, moving and transporting.

Prior to my work in this field it was sought to solve this problem and overcome these difficulties and objections by rigidly fixing or securing the condenser to the mounting and the mounting to the chassis by means of screws, bolts and the like, and perhaps by welding, but these schemes were objectionable in that they were comparatively expensive, were time consuming in initiallyinstalling the condenser and in removing for replacement and required the use of tools for installing. It is, therefore, an object of my invention to overcome these objections and to provide a suspension mounting adapted to prevent unintentional longitudinal displacement of the condenser without .being fixed thereto and is at the same time adapted to be hand pressure mounted and demounted.

The above features, advantages and capabilities of my present invention will become apparent from a description of the accompanying 4 drawing in which I have illustrated one form of my invention but the form there shown is to be understood as illustrative only and not as defining the limits of my invention except as expressed or intended to be expressed in the appended claim.

Fig. 1 is a perspective view of my improved suspension mounting showing a conventional condenser, such as used in an ordinary radio set, mounted in position for use in the usual 5 opening in the chassis. v

Fig. 2 is a top plan view showing my suspension mounting with the condenser in place.

Referring to the preferred form shown, my novelmounting device is'applied for supporting in suspension an ordinary condenser having the usual outer metal shell, The mounting comprises a metal base or supporting member I provided with a central opening. In the form shown it is of a flat annular shape, althoughi various shaped bases may -be utilized. The base is provided with longitudinally spaced sets of resilient grips 2 and 3. The members of each set extend inwardly and are resiliently opposed to other members of the same set. The longitudinally spaced resilient members in one set are in staggered relation with respect to the members in the other set. These members are constructed of resilient and tempered metal, preferably steeL'and are formed and arranged to provide longitudinally spaced resilient but firm grips on the condenser 4 or object to be mounted in place, for normally maintaining such condenser in suspension in axial' alignment with respect to the mounting device and in a predetermined longitudinally adjusted position without any extraneous supporting means and which will at the same time permit the condenser to be readily pressure mounted and demounted by hand without the use of tools.

In practice it is important that these con densers be maintained not only in vertical alignment but in a predetermined horizontal position. Due to the strains and stresses imposed upon them in use such, for example, as those imposed by a person inadvertently grasping the condenser and attempting to lift or carry the set by the condenser, or by unin'tentionally pressing down on the condenser, and others encountered in handling and transporting.

In utilizing my suspension mounting, preferably it is put into use by first pressing the mounting into a suitable opening of a slightly larger diameter, such as the opening in the pan 6 shown in Fig, 1, then the condenser 4 is grasped in the hand and moved into the opening in the mounting by a twisting or screw pressure. As the condenser is initially advanced into the opening, one set of the longitudinally spaced resilient but firm gripping members first grips the condenser, or other object which is being mounted, then as the mounted object is further moved into the desired predetermined, longitudinally adjusted position, the other set of longitudinally spaced resilient but firm gripping members likewise grips the sur ace of the object to be mounted. At this stage a fulcrum motion is set up which causes the gripping members in both sets of gripping members to impinge and resiliently but firmly grip the surface of the condenser and automatically axially align it with respect to the mounting device. When the condenser has been moved to the desired position, it is there resiliently but firmly held in such longitudinal, predetermined adjusted position without any other supporting means.

To prevent unintentional longitudinal displacement of the condenser from its predetermined position by such causes as heretofore mentioned and to facilitate the application and holding properties of my suspension mounting the ends of the upper resilient grips terminate at an angle to their plane and the leading edge is bent inwardly to form a bite 1 which when being applied first impinges and bites into the surface of the condenser. When mounting the condenser therein it is turned as it is forced into the mounting. In removing the condenser it is pulled upwardly with considerable force and concomitantly turned. It will thus be seen from the arrangement that unintentional, accidental longitudinal displacement is prevented by theordinary and accidental forces heretofore mentioned.

From the above disclosure it will be apparent that although the invention is disclosed as mounting a condenser it is adaptable for use in mounting numerous and various units or objects in a resilient but firm position in' suspension against unintentional, longitudinal displacement and at the same time is adapted to be hand pressure mounted and demounted without the use of tools, screws, nuts, bolts or the like.

Having thus disclosed the invention,

I claim:

In a suspension mounting of the class described comprising in combination a base member having an opening, longitudinally spaced sets of resilient gripping members adapted to resiliently but firmly grip a mounted object at longitudinally spaced planes for maintaining the object in axial alignment with respect to the mounting device and in a predetermined longitudinal position against unintentional longitudinal displacement, certain of said resilient grips having their contact ends terminate at an angle to the axis of the opening and integrally provided at their leading edge with means for biting engagement with said object substantially as and for the purpose set forth.
